Abstract: In this paper, the application performance of multi-functional finishing agent DM-3545 on nylon/spandex fabric was discussed. The results showed that the properties of fabric feel, hygroscopicity, fast-drying, soil release and antistatic were all improved obviously after finishing. Moreover, multi-functional finishing agent DM-3545 had little effect on the color fastness and shade of dyed nylon/spandex fabric.
